JOHN RANDOLPH SEES, OF NEV YORK, N. Y., ASSIGNOR TO WILLIAM F.

IMPROVEMENT IN FEED-WATER HEATEPLS FOR LOCOMOTIVES.

Spccilcation forming part of Letters Patent No. 42.539, dated April 26,1864.

To all whom it may concern;

Beit known that I, J oHN RANDOLPH SEEs, of the city of New York, in theState of New York, have invented a certain new and useful Improvement inFeed-Water Heaters for Lo; cornotive and other boilers; and I do herebydeclare the following to be a full, clear, and exact descriptionthereof, reference being had to the accompanying drawing, and to theletters and marks thereon.

The drawing forming part of this specifica tion shows by elevation aView of the interior of the smoke-box of a locomotive-boiler with afeed-water heater therein, which heater consists of a coil of pipe, c,the lower end thereof being in communication with the valve-chamber b,through which the feed-water parses by a pipe, c, and the upper end ofsaid coil being in communication with the water-space of the boiler by apipe, d. The valve-chamber is also shown as being in communication withthe water-space of the boiler by a circulat-ing pipe, e. Theexhaustpipesf are shown in position for discharging the exhaust-steam upwithin the coil of the heater. Around the coil at three differentpointsare shown annular bands, the same being horizontal sections of cones.These bands, g, may be at such points of the coil and in such relationto the :tire-tubes of the boiler as may be deemed best for the purposesdesigned for any special boiler in which they maybe used, and the numbermay be greater or less than here shown and named. It will readily beseen that by the use of these bands the heated products of combustion incoming out of the tubes will be interrupted in their ascent, and hencemore of the heat be given oft' to the coil. It will also be seen that byplacing these bands in line with certain portions of the tubes the drattthrough such tubes will be to some considerable extent controlled andregulated, and thus the distribution of the heated products through theupper, or the lower, or the middle portion of thetubes be made moreregular and uniform.

The annular bands g lnay be permanently affixed to the pipe of theheater by any suitable means 5 or they may be detachable or removable,so that they may readily be placed in a higher or lower position ornearer to or more remote from each other, for which purpose anyappropriate devices may be used.

That I claim as new, and desire to secure by Letters Patent, is

Surrounding portions of the feed-water heater with the annular bauds, asand for the purposes herein set forth. i

This specification signed this 30th day of September, 1863.
